Per R301.2.1.1.1 there are 5 categories of sunrooms. I through III are defined as noninhabitable space, and are unconditioned. My understanding of R303.9 is that in order to be habitable, a space must at least be heated.
Habitable space is of course defined as 1) in a dwelling and 2) for living, sleeping, eating or cooking.
Sunroom categories IV and V seem confusing.
Category IV is thermally isolated, enclosed walls, conditioned, but is *noninhabitable*.
Category V is all of the above, open to main structure, and is *habitable*.
Let's say I enclose a porch, add a mini-split, put some nice wicker furniture in there, this apparently authoritative reference is showing this as a Category IV (page 12) https://portal.ct.gov/-/media/DAS/O...s-to-the-2015-IRC_-2-Slide-Handouts.pdf?la=en
Is an enclosed porch "habitable"? Can I eat, or live out there? Or does being thermally isolated from the dwelling unit make it "nonhabitable" ?
